Theoretical study of spin-dependent transport in magnetic nanostructures using ferromagnetic insulators

我们提出了利用磁振子（自旋波）和磁振子电流作为新的自旋源的新型特征自旋电子学器件，并阐明了磁绝缘体在磁性纳米结构中的自旋输运物理。利用磁性绝缘体，如钇铁石榴石（Y5Fe2O12:YIG），我们探索了新的自旋输运现象，如涉及磁振子积累和磁振子电流的自旋塞贝克效应，为开发新的节能自旋电子器件铺平了道路。

We proposed new feature spintronics devices utilizing magnon (spin wave) and magnon current as a new spin source and elucidated the physics of spin transport in magnetic nanostructures using magnetic insulators. By using magnetic insulators, such as yttrium-iron-garnet (Y5Fe2O12:YIG), we explored novel spin transport phenomena, such as the spin Seebeck effect, involving magnon accumulation and magnon current and paved the way for development of new energy-saving spintronic devices.
